CCAN as bundled files

[Nikos Mavrogiannopoulos]

Hello,
 I've been working to include ocserv to fedora [0], but it seems there
is an issue with the rule of no bundled libraries, and CCAN [1] code
which is used in ocserv. CCAN is a repository of C code under various
licenses that can be used in any project. It is similar to gnulib, but
less oriented to portability fixed, and more into code snippets.

Is there a special permission needed to use CCAN code in a packaged
project, or the fact that there is no library is sufficient ?
